I do agree that people who who provide education and guidance wether through blogs, books, seminars or cd's deserve to earn a living from the materials they produce. I have purchased many of the books recommended on this site as well as paraliminal cd's. Every one has had some value and many are invaluable.
Perhaps my comments above were really coming from my years of thinking that a lot of PD Marketers were akin to the "Ab Buster" style of exercise equipment sellers. I have issues with pessimism.
I guess that I expect the truly enlightened professionals to take a more "natural" and quiet approach to their marketing. It may not work that way. People may be so used to being hit over the head with advertising that a softer message may not get through. I am only stating MY personal preference.
I will continue this journey however, and continue to separate the seeds of knowledge from the chaff.
Thanks for your help everyone!
